There are 2 different types of mold tests, a tape lift and an air quality test. If there is a specific area of the house has a microbial growth this can be tested with a tape lift sample to determine what type of growth it is.
An air quality sample is taken to determine what kinds of spores are in the air inside the house. A 2-sample minimum is required for this test. A sample outside and inside to compare the common outdoor spores to the speed found inside the house.
Both the tape lift and air quality samples are taken to the lab to be tested to determine what was found. From the day the sample is submitted to when the results are received are about 5 business days. A rush status can be requested for additional fee.
